permanently in adjusted position, or applied where all parts are held stationary not as hinge joints.

There has been much difiiculty in the arts, when a screw threaded bolt is used, in that accurate registration is almost impossible to obtain by mass production, manufacturers making screw threaded bolt shafts within plus and minus toleran'ces, so that of two bolts, one may have the extreme positive tolerance and the other the extreme negative tolerance. the bolt shafts were upset .to obtain a secure hold.

It has been proposed heretofore to hold a bolt shaft by means of a spring wire locked in position against rotation; This necessitates asep- In other instances,

arate hole for the anchoring of theends of the achieved by the relative close fitting circu'nif'er lences of the bolt member and the annulus. For

:more practical manufacturing conditions, the operative surfaces of the annulus are of elliptical ;shape with such dimensions relative to the circumference of the cooperating part of the bolt :member as to deform the elliptical shape to-a .circular shape in conformity with that of the oil" cularshape of the bolt member, or a circular an nulus niiay be deformed by an eccentrically acting, bolt member.

The annulus may find alternative embcdiments once with a projection, once with a bent out portion, or with other means assuring a nonrotation of the annulus. The belt member may also find alternative embodiments, once with the bolthead cooperating with the annulus, once with the nut cooperating with the annulus, or in some cases, the use of both of these embodiments in the same structure, as long as the relation of the bolthead or nut against movement in respect to v 2 each other is maintained after the desired ad-'- .justment has been established.

The invention will be further described, an embodiment shown in the drawings, and the invention will be finally pointed out in the claims.

In the accompanying drawings,

.Fig, 8 is a perspective view of a modified form of annulus such as shown in Fig. 7, and

Fig. 9 is a perspective view of an annulus with only one projection, and otherwise like that shown in Fig. 8.

Similar characters of reference indicate corresponding parts throughout the various views.

Referring to the drawings, and more particularly to Figs. 1 to 4, the movable blade A has a circular bore Ill and the relatively stationary blade B has a circular bore H. The blade B has diametrically opposed cutouts [2, made by a sawcut. One of these cutouts may be-dispensed with. Into these two registering bores, IE) and H, a sleeve bearing l5 isinserted. This sleeve bearing 15 has a shoulder l6 circumferentially disposed, anda bore 1-7, which is internally screw-threaded as shown by the threads I8. The end [9 has exgelrnal cutouts 20, and an internal counterbore A screw. 25 is externally screw-threaded as shown by 26, and has a flanged head 21, with the usual toolslot 28. The threads do not extend to the flanged head 21, but terminate in a cylindrical part 29, audit is for this reason that the counterbore 21 in the sleeve bearing [5 was provided. j

The improvement also consists in the provision of a'washer or annulus 3!), which has a base portion 31' anda rim 32 at right angles thereto, extending from one side of the base portion 3!. From the other side of the base portion 3|, extend two diametrically opposed projections 33, which have a portion 34 inclined to the plane of the base portion 3|, and another portion 35 bent into a shape parallel with the axis of the screw. These opposed projections 33 may be bent up from the 3 base portion 3|. shaped to register with the inclination of the cutouts l'2 in the blade B. The portions 35 of the projection fit into the cutouts 20 of the sleeve bearing l5.

When the sleeve bearing l5 has been inserted into the registering bores l and II until the shoulder 16 is about against the outer surface of the blade A, then the washer or annulus 3'0 is placed in position to have the projection 33 en gage the cutouts l2 and 2E]. Thereby the sleeve bearing is locked against rotation since the washer of annulus 30 is locked against rotation in respect to the blade B. Thus the blade B, sleeve bearing [5, and annulus 30, act as one member, and for that reason is properly called the stationary blade, in contrast to the movable blade A.

With the annulus 35 disposed in the position described, the screw 25 is threaded in by turning it in the sleeve bearing l5, until the flanged head 21 is forced into the rim 32 to obtain a tight frictional hold. Thereby, the screw 25, when adjusted to permit a free bearing movement of one blade in respect to the other, is held in the position desired, since it is held by frictional contact against rotation. In this embodiment, the inner diameter of the rim 32 and the outer diameter of the flanged head 2'! of the screw l5, are so dimensioned as to assure such a frictional holding contact, the outer diameter being forced within this upturned flange on these washers so as to require some force of entry.

The annulus 30 preferably has a major and 1 minor axis (Fig. 3), that is, the inner bore of the rim 32 is of ellipical shape, and the flanged head '21 then expands the minor axis to substantially the length of the major axis, or in other words, the periphery of the flanged head 21 shapes the rim 32 to its own circular periphery. The annulus shown in Fig. 4, Fig. 6, Fig. 8 and Fig. 9, preferably is also of elliptical internal rim shape.

The inclined portion 34 isis provided with a subcaliber cylindrical portion 4|, inward of its hexagonal head 42. The nut 45 of hexagonal shape has a subcaliber cylindrical portion 46.

The washer or annulus 50 has two opposed bent out projections 5| to fit into the cutouts 52, provided on each member 53 and 54, each of which has a circular bore 55, 56, registering with each other. Instead of two projections 5|, only one may be used. The'rim of the annulus 50 is dimensioned in respect to the subcaliber portions 4| and 45, as heretofore described.

The base portion of the annulus or washer is continuously circular and rigid, and the rim is likewise circular but is yieldable. The outer diameter of the entering member, be it the head of the screw or part of the nut, is equal to the average length of the maximum and minimum axes of the rim. Upon entrance of the entering member coaxially with the rim, the slightly smaller diameter corresponding to-the minimum axis of the rim is extended by the outer diameter of the entering member, and the diameter correnulus 30, only one may be used as shown in Fig. 4.

Instead of two opposed projections on the annulus 1 I, only one may be used as shown in Fig. 9. Thus, a holding washer 0r annulus'is used with a sleeve bearing for adjustment or tension of the hinge joints of the blades. 7

In Figures 5 and 6 is shown a holding washer or annulus for the conventional bolts with special bolt heads, and special nuts, namely, for other uses than shears.

In this embodiment, the screw threaded bolt 40 In Figures 7 and 8, an embodiment is shown, with a holding Washer or annulus used for adjustment or tension of hinge joints in which the bolt 60 has a flanged head GI, and its end 62 is screw threaded, and provided with flat sides 63. The washer or annulus 65 has fiat sides 66 in its base portion GI. The annulus 55 has the bent out parts 68 which engage cutouts 69 of the stationary blade 10. The nut has a subcaliber cylindrical collar 16 to engage the rim 1 l of the annulus 65. The elliptical annulus65 is dimensioned in respect to the subcaliber collar 16 as described. In this embodiment, the stationary blade 10 cooperates with a movable blade 12, as in Fig. 1. The annulus 65 has its fiat sides 66 engage the flat sides 63 of the bolt 60, and these parts are locked against relative rotation. The projections 68 engage the cutouts 69, and thus lock the washer or annulus and hence the bolt against relative rotation. The subcaliber collar 16 engages the elliptical rim ll frictionally as described, and thereby the nut is held in the desired adjusted position.

The annulus shown in Fig. 9 is like that shown in Fig. 8, but is provided with only one projection 68a.

The invention may be applied to a thread cutter of the type described in my co-filed application of August 28, 1947, Serial No. 770,976, or to any form of shears, or to such other purposes where a friction determining relationship, is desired to be maintained.

The essential is a rigid encircling non-rotative annulus of a shape expanded by the entrance of another member, whereby a relative stationary positioning of that member is secured, after it has been adjusted to proper position, and after the annulus has been locked against rotation.

I have described several forms of my invention, but obviously various changes may be made in the details disclosed without departing from the spirit of the invention as set out in the following claim.

I claim: I

In a fastening member for a pair of relatively movable members, each having a bore, said bores being in registration with each other, at least one of, said members having a cutout in its outer surface at the periphery of its bore, and means including a bolt holding the members pivotally together, the combination of a cylindrical portion on said bolt having an outer diameter larger than the diameter of the bolt, adjacent to said member with the cutout, an annulus disposed between said cylindrical portion and said cutout member, said annulus having'a base portion with a central bore for the passage of said bolt, a projection extending outwardly from the plane of said base portion at one side thereof engaging the cutout of the member, and a continuous ex pansible substantially elliptical rim marginally extending from the other side of said base portion of substantially the same inner diameter as the outer diameter of said cylindrical portion, an

5 inner diameter of the bore of said rim being less than the outer diameter of said cylindrical portion, whereby the annulus is locked to the said cutout member against rotation by the projection engaging the cutout, and said cylindrical portion is locked to the annulus by distortion of the rim, when said cylindrical portion is within the bore of the rim.
